Agent Wave

Copy this promptPrompt page

Recreate this exact single-viewport landing page for **Vesper.ai**. Document title: `Vesper.ai — Operational AI Infrastructure`. `lang="en"`. One HTML file with inline CSS and a small IIFE for the menu + animation fallback. Pure black `#000000`. No extra sections, cards, forms, pricing tables, or footer beyond the three stats. Do **not** add a video, WebGL, Three.js, or Lottie. Do **not** invent a CloudFront URL.

Force black immediately so the page can never flash white:

- First CSS rule: `html, body { background: #000000 !important; color: #ffffff; }`
- Body attribute: `style="background:#000;color:#fff"`
- Then again: `html, body { background: #000000; background: var(--bg, #000000); color: #ffffff; color: var(--text, #ffffff); }`

### Fonts (exact)

Self-hosted WOFF2s sitting next to `index.html`:

```css
@font-face {
  font-family: "Inter";
  font-style: normal;
  font-weight: 100 900;
  font-display: swap;
  src: url("inter.woff2") format("woff2");
}
@font-face {
  font-family: "Instrument Serif";
  font-style: italic;
  font-weight: 400;
  font-display: swap;
  src: url("instrument-serif-italic.woff2") format("woff2");
}
```

Stacks:

- UI / logo / nav / buttons / badge / lede / stats: `"Inter", system-ui, -apple-system, BlinkMacSystemFont, "Segoe UI", sans-serif`
- **Only** the H1 words `AI agents`: `"Instrument Serif", "Times New Roman", Times, serif`

If those files are missing, load this exact Google Fonts CSS (Inter variable roman + Instrument Serif italic only):

```
https://fonts.googleapis.com/css2?family=Inter:ital,opsz,wght@0,14..32,100..900&family=Instrument+Serif:ital@1&display=swap
```

Body: `-webkit-font-smoothing: antialiased; -moz-osx-font-smoothing: grayscale; text-rendering: optimizeLegibility; overflow-x: hidden; position: relative`. `html { scroll-behavior: smooth }`. Universal reset: `box-sizing: border-box; margin: 0; padding: 0`. Links `color: inherit; text-decoration: none`. Buttons `font-family: inherit`.

### Image / asset URLs (exact — there are only these)

**1. Herovide obackgorumf 100% opacity no overlay**  
Relative file, same folder as the HTML:

```
https://meez.design/web/media/ext/fcb85f8b52447bb5.mp4
```

**3. Favicon (exact data URI)** — same mark as the logo, white:

```

### Layer stack (back → front)

1. `html/body` black  
2. `.hero-photo` + `::after` scrim  
3. `.page` — `position: relative; z-index: 1; display: grid; grid-template-rows: auto 1fr auto; min-height: 100vh / 100dvh`  
4. `.grain` at `z-index: 100`

Markup order inside body:

```

### Header — 3-column grid

`display: grid; grid-template-columns: 1fr auto 1fr; align-items: center;`  
Padding: `var(--header-y) var(--header-x) 10px`. `z-index: 50; position: relative`.

`display: inline-flex; align-items: center; gap: 9px; justify-self: start; font-size: var(--logo); font-weight: 600; letter-spacing: -0.03em; color: #fff`.

Mark SVG 22×22, `viewBox="0 0 24 24"`, `fill="currentColor"`, group `transform="rotate(-30 12 12)"`:

`border: 1px solid rgba(198,198,198,0.55)`

Transition: `background / border-color / box-shadow 0.35s ease`.

Shine `::before`: `linear-gradient(115deg, transparent 30%, rgba(255,255,255,0.16) 50%, transparent 70%)`, idle `translateX(-120%)`, hover `translateX(120%)` over `0.6s ease`.

Hover: border `rgba(235,235,235,0.9)`, gradient `#111 → #3a3a3a 45% → #6a6a6a`, glow `0 0 18px rgba(200,210,230,0.18)`.

**Right — header CTA:** `a.btn.btn-solid.header-cta.appear.appear--scale` “Start for Free” → `#start`, `justify-self: end`.

**Burger** (hidden ≥901px, `display: none` → `display: grid` on phone): 42×42, `border-radius: 6px`, `border: 1px solid var(--border)`, `background: rgba(8,8,8,0.55)`, `z-index: 60`, `aria-controls="site-nav"`, `aria-expanded="false"`, label “Open menu”. Three white bars 16×1.5px, gap 5px, `border-radius: 1px`. Hover: border `rgba(255,255,255,0.32)`, bg `rgba(255,255,255,0.05)`.

### Stats footer

`.stats`: flex, `align-items: center; justify-content: space-between; gap: 24px;`  
padding `0 var(--stats-x) var(--stats-y)` and `padding-bottom: max(var(--stats-y), env(safe-area-inset-bottom))`, color `#d8d8d8`.

Each `.stat.appear.appear--stat`: `inline-flex; align-items: center; gap: 14px; font-size: var(--stat-size); letter-spacing: -0.015em; white-space: nowrap`. Icon 20×20 (`#e8e8e8`). Wide avatar icon 38×21.

**1. Dual-pill / workflow icon** (`viewBox="0 0 24 24"`):  
Left rect `x=3.4 y=2.6 w=7.2 h=18.8 rx=3.6` fill linear `#ffffff@0.38 → #3a3a3a@0.62` (`x1=3 y1=2 x2=14 y2=22`).  
Right rect `x=13.4 y=2.6` same size, inverted `#3a3a3a@0.38 → #ffffff@0.62`.  
Connector `x=9.2 y=10.9 w=5.6 h=2.2 rx=1.1` fill `#4a4a4a`.

**2. Download tile:** white rounded square `x=2.4 y=2.4 w=19.2 h=19.2 rx=6.2` fill `#ffffff`. Arrow `#111` stroke-width `1.85` round: vertical `M12 7.1v7.4`, chevron `M8.15 12.35L12 16.2l3.85-3.85`.

Label: `180+ operational teams onboarded`

### Entrance motion (exact)

`.appear` resting opacity is **1** (so the page is never blank if animations fail).  
`animation-duration: 1.05s; animation-fill-mode: both; animation-timing-function: cubic-bezier(0.16, 1, 0.3, 1); animation-delay: var(--d, 0.08s)`.  
`both` applies the 0% keyframe during the delay, so they still hide then fade in when animations run.

On each element’s own `animationend`, add `.is-in` (`animation: none; opacity: 1; transform: none; clip-path: none; filter: none`). Same for `.hero-photo.is-in`.

JS fallback: after two `requestAnimationFrame`s, if `el.getAnimations()` has nothing `running` or `finished`, add `.is-in` to every `.appear` and `.hero-photo`.

Keyframes (all end at opacity 1 / identity transform):

- `in-scale`: `opacity 0, scale(0.84)` → 1  
- `in-soft`: `opacity 0, translateY(14px)` → 0  
- `in-mask`: `opacity 0, translateY(40%)` → 0 (clipped by `.headline-line` overflow)  
- `in-pop`: 0 `scale(0.9)` → 70% `scale(1.03)` → 100% `scale(1)`  
- `in-btn`: `translateY(18px) scale(0.94)` → rest  
- `in-side`: `translateX(22px)` → 0  
- `in-stat`: `translateY(20px)` → 0  
- `in-star` on `.badge-star`, `0.9s`, delay `0.28s`, both: `scale(0.2) rotate(-50deg)` → 65% `scale(1.2) rotate(8deg)` → rest  
- `in-em` on `h1 em`, `1.2s`, delay `0.72s`, both: `opacity 0.35; filter: blur(4px)` → sharp  

`prefers-reduced-motion: reduce`: `transition: none !important; animation: none !important` on `*, *::before, *::after`. Force `.appear, .hero-photo, .hero h1 em, .badge-star` to `opacity: 1; transform: none; clip-path: none; filter: none`.

### JS (only this)

1. Each `.appear` → own `animationend` → add `is-in` (`once: true`).  
2. If animations are not running after two rAFs, force `.is-in` on all `.appear` and `.hero-photo`.  
3. Burger toggles `body.menu-open`.  
4. Nav links and Escape close the menu.  
5. Resize to `(min-width: 901px)` closes the menu.
